What are the characteristics of the new energy vehicle temperature sensor?

The new energy vehicle temperature sensor refers to a device or device that can sense a prescribed physical quantity and convert it into a usable input signal according to a certain rule. In simple terms, a sensor is a device that converts non-electricity into electricity. Sensors usually consist of three parts: sensitive components, transducer components, and measurement circuits.

1. The sensitive element refers to the part that can directly feel (or respond) to the measurement, which is about to convert the sensitive element of the new energy vehicle temperature sensor to be measured into a non-electricity or other quantity that has a definite relationship with the measurement.

2. The conversion element converts the above-mentioned non-electric quantity into electrical parameters.

3. The function of the measuring circuit is to convert the electrical parameters input by the conversion element into a measurable amount of voltage, current, or frequency after processing, to display, record, control, and process the part.

What is the parameter index for the static characteristics of the new energy vehicle temperature sensor?

1、Sensitivity

Sensitivity refers to the ratio of sensor output y to input x or the ratio of the increase of output y to the increase of input x expressed as k=dY/dX.

2、Resolution

The smallest amount of change that the sensor can detect within the specified measurement range is called the resolution.

3、Repeatability

Repeatability refers to the inconsistency of the characteristic curve obtained by continuously changing the input quantity in the same direction in the whole measurement range many times under the same working condition.

4、Zero drift and temperature drift

When the sensor has no input or the input is another value, at regular intervals, the percentage of the maximum deviation of the input value from the original display value and the full range is zero drift. And for every 1°C increase in temperature, it is the percentage of the maximum deviation of the output value of the energy vehicle temperature sensor from the full range, which is called temperature drift.

5、Measuring range and measuring range

Within the permissible error limit, the range from the lower limit to the upper limit of the measured value is referred to as the measuring range.

6、linearity (nonlinear error)

Under certain conditions, the percentage of maximum deviation between the sensor calibration curve and the fitted line and full scale is known as linearity or nonlinear error.

What is the market situation of temperature sensors for new energy vehicles?

As the information source of the automotive electronic control system, the new energy vehicle temperature sensor is a key component of the automotive electronic control system and one of the core contents of the research in the field of automotive electronic technology. It measures and controls various information such as temperature in real-time and accurately. The key to level measurement in modern high-end car control lies in the number and height of its sensors.
